Averaging of the data depends on the sample and the method used.

Examples
示例
In the potentiometric determination of pH value, the reportable result is determined by calculating the average of a number (for example 3) of measurements of a sample, and this average is reported as the test result.
在pH值的電位測定中,通過計算樣品測量值的平均值(例如3)來確定報告結果,并將該平均值報告為測試結果。
For an HPLC method for assay of active substance, one independent determination has been carried out by three consecutive injections (replicates) of the same sample preparation. The reportable result is determined by averaging the peak responses from these replicates obtained from the same preparation. The assay result is calculated using the peak response average. This determination is considered as one test and one reportable result, and should fulfil the predefined acceptable precision criteria, e.g. based on validation criteria.
對于用于測定活性物質的HPLC方法,已通過連續三次進針(重復)相同的樣品溶液進行一次獨立的測定。通過對從同一溶液中獲得的這些重復的峰響應求平均值來確定可報告的結果。使用峰值響應平均值計算測定結果。該測定被視為一項測試和一個可報告的結果,并應滿足既定的的可接受精度標準,例如基于驗證標準。
同時也提出:
When evaluating results of microbiological contamination tests it is important to note that the contamination may not be distributed evenly throughout a product batch or sample. Homogeneity of a microbiological sample, for example, by thorough mixing prior to testing, does not imply a constant level of microbial cells throughout test sample units. Where the contamination is not uniformly distributed throughout a product batch or sample, i.e. contamination is detected in some but not all of the units, it may not be valid to pool and then average the count results from multiple units of the sample as this could average out a non-compliant result to a compliant result.
在評估微生物污染測試結果時,重要的是要注意污染可能不均勻地分布在整個產品批次或樣品中。微生物樣品的均勻性,例如,通過在測試前徹底混合,并不意味著整個測試樣品單元的微生物細胞水平恒定。如果污染在整個產品批次或樣品中分布不均勻,即在某些而非全部單位中檢測到污染,則合并然后平均多個樣品單位的計數結果可能無效,因為這可能會將不合格結果平均為合格結果。
